Template:DisplayEquation

The template takes two named parameters, eqn and no, being the LaTeX expression and the equation number respectively. Both parameters are optional, but only two combinations are useful:

{{DisplayEquation|eqn=a^2+b^2=c^2}}

$\displaystyle {a^{2}+b^{2}=c^{2}}$

{{DisplayEquation|no=28|eqn=\frac{\partial\rho Y_k}{\partial t}
+\frac{\partial\rho u_iY_k}{\partial x_i}=
\frac{\partial}{\partial x_i}\left(\rho D_k\frac{\partial Y_k}{\partial x_i}\right)
+\dot{\omega}_k\qquad \text{for } k=1,2,\dots,N}}

$\displaystyle {{\frac {\partial \rho Y_{k}}{\partial t}}+{\frac {\partial \rho u_{i}Y_{k}}{\partial x_{i}}}={\frac {\partial }{\partial x_{i}}}\left(\rho D_{k}{\frac {\partial Y_{k}}{\partial x_{i}}}\right)+{\dot {\omega }}_{k}\qquad {\text{for }}k=1,2,\dots ,N}$

$\left(28\right)$

Note that equation labelling is not restricted to numbers:

{{DisplayEquation|no=\text{axiom }M3|eqn=\rho(a,c)\le\rho(a,b)+\rho(b,c)}}

$\displaystyle {\rho (a,c)\leq \rho (a,b)+\rho (b,c)}$

$\left({\text{axiom }}M3\right)$
